Entity definition

IfcPropertyEnumeration is a collection of simple or measure values that define a prescribed set of alternatives from
which 'enumeration values' are selected. This enables inclusion of enumeration values in property sets. IfcPropertyEnumeration
provides a name for the enumeration as well as a list of unique (numeric or descriptive) values (that may have a measure type
